Heating apparatus, dryer, and printer

Abstract

A heating apparatus includes a plurality of heaters to heat a heating object, a plurality of air nozzles to blow air onto the heating object, and a blower to supply air to the plurality of air nozzles. The plurality of heaters is disposed along a conveyance direction of the heating object, at least one of the plurality of air nozzles is disposed between adjacent two of the plurality of heaters, and the plurality of air nozzles blows air onto the heating object while the plurality of heaters heats the heating object in both cases of when the heater performs a heating operation and when the heater does not perform the heating operation.

What is claimed is: 
     
       1. A heating apparatus, comprising:
 a plurality of heaters to heat a heating object, the plurality of heaters disposed along a conveyance direction of the heating object; 
 a plurality of air nozzles to blow air onto the heating object, at least one of the plurality of air nozzles disposed between the plurality of heaters; 
 a blower to supply air to the plurality of air nozzles; and 
 a heating controller to control a heating operation of the plurality of heaters; and 
 an apparatus power supply to supply power to the heating controller via a first power supply route, and to supply power to the blower via a second power supply route, the first power supply route and the second power supply route are separate, 
 wherein the blower supplies the air to the plurality of air nozzles in both cases of when the plurality of heaters performs the heating operation and when the plurality of heaters does not perform the heating operation while the apparatus power supply is turned on so that the air nozzles continue to blow air so long as the apparatus power supply is not turned off. 
 
     
     
       2. The heating apparatus according to  claim 1 , wherein the air blown onto the heating object from the plurality of air nozzles passes through a periphery of the plurality of heaters and is discharged outside the heating apparatus. 
     
     
       3. The heating apparatus according to  claim 1 , wherein the plurality of heaters is arranged in rows in the conveyance direction of the heating object, and
 the plurality of air nozzles is disposed on an upstream end and a downstream end of the rows of the plurality of heaters in the conveyance direction of the heating object. 
 
     
     
       4. The heating apparatus according to  claim 1 , further comprising an exhaust to discharge the air blown onto the heating object outside the heating apparatus,
 wherein the exhaust discharges the air outside the heating apparatus in both cases of when the plurality of heaters performs the heating operation and when the plurality of heaters do not perform the heating operation. 
 
     
     
       5. The heating apparatus according to  claim 4 , wherein
 power supplied to the exhaust is supplied via a third power supply route and the exhaust is controlled by turning on or turning off the apparatus power supply. 
 
     
     
       6. A dryer comprising the heating apparatus according to  claim 1  to dry the heating object. 
     
     
       7. A printer comprising:
 the dryer according to  claim 6 ; and 
 a liquid application unit to apply liquid to the heating object before the heating object is conveyed to the dryer.
